ISO 12111:2011 is applicable to the TMF (thermomechanical fatigue) testing of uniaxially loaded metallic specimens under strain control. Specifications allow for any constant cyclic amplitude of mechanical strain and temperature with any constant cyclic mechanical strain ratio and any constant cyclic temperature-mechanical strain phasing.
Abstract
Overview
ISO 12111:2011 - Metallic materials - Fatigue testing - Strain-controlled thermomechanical fatigue testing method - defines a standardized method for performing strain-controlled thermomechanical fatigue (TMF) tests on uniaxially loaded metallic specimens. The standard covers simultaneous, cyclic control of mechanical strain and temperature, allowing any constant cyclic amplitude, mechanical strain ratio and temperature–strain phasing. It targets reproducible generation, monitoring and reporting of TMF data for materials subject to combined thermal and mechanical cycling (commonly in the low‑cycle fatigue domain).
Key topics and technical requirements
- Scope and definitions: Terms for total, thermal and mechanical strain; cycle, amplitude, range, phase angle and fatigue life are defined to ensure consistent usage.
- Apparatus:
- Tension–compression testing machine with smooth, backlash‑free start-up (hydraulic or electromechanical).
- Force measuring system compliant with ISO 7500‑1 Class 1.
- Strain measurement (extensometer) conforming to ISO 9513 Class 1 (Class 0.5 recommended for gauge lengths
